CHARLES SUMNER TARREN, OF TORON"O, ONTARO, CANADA.

STOP-ACTION FOR REED-ORGANS.

SPECIFICATION forming part of Letters Patent No. 425,156, dated April 8, 1890.

Application tiled February 23, 1889. Renewed February 13, 1890, Serial No. 340,274. (No model.)

T0 all whom t 11i/Coy concern:

Beit known that l, CHARLES SUMNER VAR- RENLof the city of Toronto, in the county of York and Province of Ontario, Canada, have invented certain new and useful Improve ments in Stop-Actions for Reed-Organs; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to the stop-actions of reed-organs of one or more manuals, and is more especially designed for use in connection with that superior class where there are end wind-trunks and a series of wind-chests and different rows of reeds arranged one above the other, as in my former application tiled March 22, 1888, Serial No. 268,163.

My improvements have for their object to adapt a pneumatic stopeaction to this class of instrun'lentsthat is to say, where the organ is of the pressure class in ,contradistinction to suction organs.

By the special features of construction, novel elements, and combinations of parts embodied in this invention 1 obviate all the diiculties and objections heretofore experienced in operating slides, hinged flaps, and such like devices in reed-organs of this kind for controlling the wind between the main windLtrunk and the several wind-chests and reed-chambers, and produce a stop-action at once noiseless, positive, and easy and efficient in operation.

For full comprehension of the invention and of the several features of construction, reference must be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate like parts.

In said drawings, Figure 1 is a plan view illustrating several stops and levers in connection therewith Jfor operating the pneumatic valves. Fig. 2 is a vertical sectional elevation (looking at the rear of Fig. 1) showing said levers in connection with said valves, the valve-chest, main win d-trunk, win d-chests, and my devices for controlling the wind between the same. Fig. 3 is a face view (on ren duced scale) of the wind-trunk, showing ar rangement of air-pipes between valve-chest and pallets covering openings to the several wind-chests. Figs. 4, 5, and 6 are respect ively a plan, horizontal section, and end view of the pallet in its relation to the wind-chest. Fig. 7 is a bottom plan of the valvechest and valves. Fig. 8 is a top plan of the same, the casing' being in section. Figs. E) and 10 are horizontal sectional elevations illustrating a stop-lever, thevalve it controls, and the valve chest, the same showing the valve in its open and closed positions, respectively.

A represents a horizontal part of the organ case or frame, and A the front board or stopjamb through which the several stop-rods 1 2 3 A1 work.

Bis the main wind-trunk, situated vertically at the end of the instrument, and extending horizontally from this from end to end are the several wind-chests C C C2, tbc., these being placed one above the other, as is usual in this class of organs, it being understood that the reeds are arranged in the same horizontal plane in connection therewith.

For the sake of clearness l will describein detail only one stop and its connections; but may here state that there is one stop for each wind-chest and its series of reeds.

Taking the stop marked 1 as controlling the'nppermost wind-chest C, (shown in Fig. 2,) to the inner end of the stop-rod is pivoted a connecting-rod D, preferably bifurcated at its outer end, so as to embrace the bent arme of a crank-rod or roller E, which is journaled horizontally upon the board A in bearings a a at each end, so as to be turned laterally therein by the movement of the stop-rod 1. At or near the other end of this crank-rod E is another bent arm c', which, when the crank e assumes its vertical position, as seen in Fig. 2, impinges against and forces up one end of a spring valve-lever F, hung at f from the bottom of a valve-chamber G, thus depressing its other end, upon which is a proper disk f', and opening a port g previously covered by said disk. This port extends completely through the bottom of the valve-chamber G, its upper end being controlled by a iiat spring-valve G', contained within. the chamber G, from the face of which depends a wire or spindle g, passing down through the port g, being just long enough to project below the mouth of said port, where it is surmounted by abutton g?, as shown in Fig. 9. )Vhcn the parts are in this position, the inner valve G is kept closed by its spring G2 and the lower valve is kept IOO operi, as described. XVhen the stop-rod l is not drawn out, the crank-arm e is out of connection with the valve-lever F, and this lower valve is kept closed by the spring F, (which is stronger than the spring G2,) and the disk f', pressing up against the button of the wire g, forces the valve G up and away from its seat, and thus throws the port g into communication with the valve-chamber G, this being its normal position,as indicated in Fig. l0.

intersecting the port g is a passage h, preferably made in the bottom board ci' the valvechamber, and this is in communication with a conductor or pipe H, preferably extending up through the wiiid-trniik ll and forming j unctioii with a block 7a, perforated internally, so as to communicate with a small bellowspallet K, carried thereby. This block k being affixed to the divisioii-board between the windtruiik and wind-chest C, the loose board of the pallet is adapted to cover the conimunieatin g orifice e by which the wind passes from the former to the latter. In pallets of this kind the leather is generally lett somewhat loose at the hinge-joint k', and the moving board is consequently liable to sag, and thus improperly cover the opening c. Therefore I attach one end of a spring L to the edge of the moving board and the other to the pallet-block 71:, which serves the double purpose of bracing up the hinge-joint and assisting to keep suoli moving board closed, it being` remembered that the air-pressure from both sides is about evenly balanced. Uien the stop-rod is pushed in, the valve F is closed and the valve G open, and the valve-chamber G being always in conini unieation with the wind-trunk B by means of the orifices h h, (shown in Fig. 8,) consequently the wind is iilling the conductor ll and pallet K, iniating the latter and causing it to stop the orifice c and eut off that particular windeliest. Upon the pulling out of the stop-rod, the closing ol the valve G, and opening ot' valve F, in the manner already explained, the wind is shut oil, and that heretofore inflating the bellows-pallet passes out through the open port g, the pallet being forcibly collapsed by the compressed air contained in the windtrunk and the wind admitted from the trunk B to the wind-chest desired through the oriiice c.

lVliat I claim, and desire to secure by Letters Patent, is as follows:

l. rPhe eoiiibinatioii,with the stops, the windtrunk B, and win d-eliests C, of the valve-chainber G, having a series of valves G therein, said chamber being common to all the valves and having a bottom board formed with a series of passages 7L and a series of ports g extending transversely thereof, the conducting-pipes H, leading 'from the passages 7i. and extending throi'igh the wind-chest 13,' the valves F below the valve-chamber, and the collapsible pallets K, substantially as described.

2. The coinbination,with the stops,the windtrunk B, and the chests C, of the valve-chamber G, having a series olstein-valves G and having passages 71l communicating therewith through transverse ports g, the pivoted levers F, carrying the valves j, and the crank-rod c, connected to the stop for operating said lever.

The combination, with the valve-chamber G, having port g, of the valve G2, located within said chamber and' having rod or wire g projecting through said port, and the external spring valve-lever F, adapted to engage with said rod or wire, substantially in the manner and for the purpose specified.

a. The combination, with the collapsible pallet and block carrying saine, of the spring li, for the purpose described.
